Copper Flexible BusBars For Lithium Battery
Copper Flexible BusBars for Lithium Battery are flexible conductive components specifically designed for high-current battery system connections, primarily used in power battery packs, energy storage systems, electric vehicle battery modules, and high-power power electronic devices. Their core structure is typically formed by laminating multiple layers of high-purity copper foil, using diffusion welding or high-voltage pressing processes to create a monolithic conductor, thus providing necessary mechanical flexibility while maintaining high conductivity.

Product Introduction
This Copper Flexible BusBars for Lithium Battery is a core high-current flexible conductive connector for PACK and energy storage systems. It is specifically designed for vibration buffering, thermal expansion and contraction compensation, confined space wiring, and high-current low-loss transmission in lithium battery operating conditions, distinguishing it from traditional rigid copper busbars and cables. The product uses high-purity electrolytic copper substrate, formed through a laminated composite, precision welding, and integrated insulation encapsulation process. It complies with IATF16949 automotive and energy storage industry standards, is suitable for automotive and energy storage environments, and meets RoHS and REACH environmental regulations. It is a key component for reducing losses, improving stability, and preventing safety hazards in lithium battery systems.
Design Advantages
The Insulated Flexible BusBar is suitable for lithium battery thermal cycling and vehicle vibration conditions. It features multi-layer copper foil gradient stacking, matching the coefficient of thermal expansion, actively dissipating deformation stress, and preventing cracking of the hard copper busbar top support. The number of copper foil layers can be customized as needed, taking into account both current carrying cross-sectional area and flexibility, adapting to dynamic scenarios, and extending module life.
Fitting the PACK module mounting interface with CNC precision positioning and hole opening, with a hole tolerance of ±0.05mm, accurately matching the battery terminal dimensions, eliminating assembly misalignment and loose connections; supporting customized irregular holes and multiple sets of parallel holes, eliminating the need for secondary processing, compatible with automated production lines, improving Laminated Flexible BusBar assembly efficiency and reducing debugging costs.
Compatible with DC1500V and 800V high voltage platforms, featuring full insulation coverage and end flange design to prevent creepage and short circuits; pre-reserved temperature measurement and EMC shielding points; integrated with multiple functions requiring no additional accessories; the Flexible Insulated Copper BusBar balances safety and heat dissipation, meeting vehicle and energy storage high voltage safety standards.
